Incorrect. 40 to 1 is leaner than 32 to 1. On a 2 stroke when it runs rich it's because it has too much oil, and the oily gas saturates the spark plug. 32 to 1 would be 4 ounces of oil to 1 gallon of gas. 40 to 1 would be 3.20 ounces of oil to 1 gallon of gas.

I learned the little that I know from a guy who raced motocross for longer than you and i have been alive combined. Oil burns hotter than gas and therefore actually helps to keep from fouling the plug. More oil = less fouled plugs. Counter intuitive and probably goes against the status quo, but it works.

Man right now the only thing the 250 has on your bikes is cheap and longer lasting tires! I get between 50-55 on the usual. But the unusual thing is, I still get between 50-55 if I hit the twisties. The most I've ever gotten is 61, and the least I've ever gotten is 41.

I was getting about 65 mpg on average on my 07 Ninja 250. But once when I was trying to see how high it would go, I rode it really easy and hit 79 mpg.

2007 Kawasaki ninja 250. I know its small I'm not a novice rider by any means (been riding dirt bikes since I was 8 and 25 now) didn't need a 600 or bigger. I might do one later but for now I'm happy with it.

That bike looks almost exactly like my last bike. It was a blue 07 Ninja 250 and I removed the flames as well. I have 2 suggestions for you.

1. Get better tires. Those are the tires that came on that bike and they SUCK. You won't believe how much better tires will change the way that bike rides. I went with Bridgestone Battlax BT45s.

2. Once you're comfy with the bike, replace the stock throttle body with an R6 throttle body. With the stock throttle body you can't go wide open throttle (WOT) with one twist of the wrist. You have to twist it, re-grip it, and then twist again. With the R6 throttle body, one full twist is WOT. While it doesn't actually make the bike any faster, it makes the throttle more responsive which makes it quicker.

And one of the coolest things about the old Ninja 250s is that they have a great online community. Check out the 250 Riders Club athttp://forums.ninja250.org/

The Technical and Repair section there has anything you ever wanted to know about that bike.

That's not true. At 37 I had full coverage on a Ninja 250 and paid $300 a year. Full coverage for my 18 year old brother on a Ninja 250 is $99 a month.

I'm willing to bet you've never even see what a fouled 2 stroke plug looks like. It's saturated in oily gas. That is what fouls it. More oil, the leaner the mixture of gas and oil, meaning the plug will foul easier due to more oil soaking it. It's opposite of a 4 stroke. Why do you think a 2 stroke when running 32 to 1 fouls plugs easier than a mixture of 40 to 1? Why do you think a 2 stroke has splooge running out of the silencer on a mixture of 32 to 1 on a 70* day? Your friend is wrong.

My father, uncle, and my experience racing motocross combined is over 100 years, and we have the trophies to prove it. You've never even done it, so what do you know?

I think you mean throttle tube, not throttle body, I could be wrong though.

Also FWIW I pay $19/month for everything except for bodily damage (rejected by insurance obviously) on my 02 Monster. For my 04 ninja 250 I paid $30 a month for equal coverage.

Yes, that's why at 32:1 splooge will run out of your exhaust even at moderate spring temperatures. It's too lean, there is too much oil, and the oil fouls your plugs. It has not a thing to do with horsepower. 40:1 has been the stand by for years by many racers. It is the perfect balance between oil and gas so your plugs aren't fouled.

Every fouled plug I have pulled out of a bike has been on break in with 32:1 ratio, and it was oil fouled like your typical spark plug. I don't care what the article's say. Instead of writing about it, they should get out there on a sunday and ride and find out the truth that 32:1 is too lean and should only be used in break in sessions.

Clearly those guys have never gotten out there on a sunday and ridden. They don't know what they're talking about.

Doesn't sound like you read either article completely because you didn't get the main idea of either.

Saying 40:1 or any other ratio is some magical "perfect balance" is completely retarded. I don't have to know much about anything to know that. Every bike is different.
